John Hancock Financial Services is extending its Promises advertising campaign.

Hancock, Boston, a unit of Manulife Financial Corp., Toronto, is spending about $25 million to $35 million on the current phase of the campaign, the company says.

One of the 3 new 30-second television spots, “House,” shows a man who wants to take care of his aging parents.

Another shows a business owner who wants to leave his business to his daughter, and a third shows an architect who wants to become a teacher.

Hill, Holliday, Connors, Cosmopulos, Boston, created the commercials which will air on cable channels such as CNN, ESPN and Discovery.

The campaign also includes full-page, four-color ads in print publications such as Sports Illustrated and National Geographic, and it includes Web ads and ads on the front page of the Personal Journal section of the Wall Street Journal, Hancock says.
